In the sphere of data management and cybersecurity, data classification stands out as a critical function that helps users optimize data handling processes. When preparing for the SC-900 Microsoft Security, Compliance and Identity Fundamentals exam, you should understand how data classification capabilities aid in managing data security, compliance, and identity.
Data Classification Overview
Data classification is the process that involves categorizing data based on defined criteria. This mechanism enables organizations to effectively manage and secure their data across different levels. Data classification can occur in three primary categories;
- Public: Data in this category is open to all or most people within or outside the organization.
- Sensitive: Sensitive data comprises information that, if exposed to unauthorized individuals, can cause considerable harm or loss.
- Private: This data is often encrypted, and only authorized individuals can access it.
Understanding the above data classification structures enables you to handle data according to its sensitivity level, which guarantees optimized data management and enhanced security.
Data Classification Capabilities in Microsoft Security
Microsoft’s security, compliance, and identity capabilities use data classification to assist organizations in enhancing their data management structures. The Microsoft 365 compliance center facilitates data classification using features such as trainable classifiers, built-in classifiers, and sensitivity labels.
Trainable Classifiers
Microsoft 365 enables users to design and train classifiers to suit their data configuration needs. A trainable classifier categorizes your data, and you can ‘train’ it to understand what data it should identify.
Built-in Classifiers
Built-in classifiers come preconfigured in your Microsoft 365 compliance center. They serve to identify and categorize standard data types such as credit card information, social security numbers, bank account numbers, and more.
Sensitivity Labels
Sensitivity labels in Microsoft 365 compliance center help to classify and protect data. For instance, you can create sensitivity labels to identify and automatically encrypt financial data.
Examples
For instance, if you have a data set comprising of credit card information, you can utilize the predefined ‘credit card information’ built-in classifier to identify this data throughout your Microsoft 365 environment.
In the case of trainable classifiers, you can design one to identify data containing certain phrases your organization regularly uses. With machine learning, you can train this classifier to recognize this information across your data landscape.
A sensitivity label example would be creating a ‘Financial Data’ label that applies encryption automatically to data identified as such.
Using these powerful data classification capabilities can greatly enhance your data management structures. It ensures controlled access, effective handling, and safe storage of data based on its category. Having a comprehensive understanding of these capabilities is crucial for the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam.
Get started in enhancing your knowledge and application of these capabilities and stand a chance to optimize your data handling and management needs.
